ISR AG

ISR AG is a unique, highly crack resistant concrete developed by Conproco and its partners in an ambitious research project commission by the U. S. Navy. The Navy requirements were to develop a repair material with a high resistance to cracking and maximize the use of recycled materials. ISR or Internal Stress Relief technology is the result of a three-year laboratory and field effort. Every test for a repair material listed in the ACI/ICRI Data Sheet Protocol has been conducted by independent laboratories on ISR AG. The material handling characteristics are exceptional in that it can be placed up to a 8” – 9” slump without effecting material properties.
